This invention relates to an improved engine, which may be applied tothe class of internal combustion engines and also steam en ines oroutside the class of prime movers it 1s adapted for the construction ofpumps.

An object of the invention is to prov1de an engine in which the numberof parts is reduced to the minimum thereby decreasing the chances ofaccidental stalling of the enne. This makes it a highly desirable engineor aircraft.

Another object of the invention is to provide a cooling system of simpleconstruction which insures an even proper temperature for the parts ofthe engine.

Another object of the invention is to utilize the piston, which is inthe 'form of a wobblep'late, for keeping the inside of the cylinderclear of carbon and to eliminate uneven wear on the cylinder walls.

The invention is' illustrated in the accompanying drawings in whichFigure is a section of an engine embodying m mvention. Figure 2 is asection of a modified f orm and Figure 3 is a section of anothermodified form.

The invention is designed to employ the re quired number of units todevelop the required power, each unit comprislng a cylmder and awobble-plate is confined in the cylinder so that its periphery passesthrough a fixed channel at one point in the cylinder. This causes thewobble-plate to move longitudinally except at this point and eithermoves on its shaft or the shaft is mounted tol move longitudinally tothek desired extent.

In the construction of the engine the usual form of cylinder is one withinclined ends that are at opposed angles and are thus in planes thatconverge. l

The wobblelate is of a depth to iit in the narrow part o the cylinderand when rot-ated passes throu h this narrow part, the portion of thewob le-plate not in this part being free to travel a limitedlongitudinal path determined by the pitch or angle of the wobble-plate.

In Fi has the inclined ends 11 and 12, these ends being in planes thatconverge and I show a gure 1 I show the cylinder 10 which' secondcylinder 13 which has similar ends 14: and 15. The construction providesnarrow portions 16 and 17 of the respective c linders.

The cylinders are each provide with a wobble plate 18 which isproportioned to fit approximatel inthe narrow portions of theirrespective cy inders. As the wobble plates rotate they. pass throughthese narrow p0rtions and also move longitudinally in the cylinders. Theshaft 19 is secured to the cylinders and moves with them. It slides inthe bearings 20. In this particular construction the outer ends ofthecylinders are the chambers which act as the propelling or explosionVchambers according to whether it is a steam or internal combustionengine. I show a spark plug 21 to indicate such explosion end of acylinder.

The shaft causes the cylinders to move in unison and it is shown askeyed at 22 to the sprocket or gear 23 which is coupled to the mechanismto be driven. l

In each cylinder I show an exhaust port 24, an inlet port 25 andahy-pass 26, all these disposed to be opened .and closed by thewobble-plate in each cylinder.

The engine shown in Figure l is in position for explosion of a mixturein the end l1 of the left hand unit or cylinder. -This will force thewobble plate to the other end of the cylinder and rotate it a one-halfturn, this compresses the mixture on the other side of the wobble-plateand it is propelled through the byjpass 26 as the openin s 27 and 28come in register with the two en s of the by-pass.

The opening 28 is a slit and the by-pass is Vformed to become broad andflat at its outlet -each as a two-cycle unit and the co-operation makesfor a continuous smooth motion of the shaft 19.

The holes 34come in line or re 'ster with the holes 35 at the same timean allow oil to ass out by centrifugal force into the chamber 1. Thisforces an intermittent flow of fluid which is preferably oil and the o1lpasses out at 32'l and is then again brought back to 32 by any form ofreturn means. This o1l 1s wiped along the inside wall of the cylinder bythe wobble plate, as the hole 34 passes along in a helical ath and thiskeeps the inside wall of the cyliner properly lubricated. The deosits ofcarbon on the inside wall of the cylinder are removed, as they form, bythe edges of the wobble-plate.

These edges are more efficient when they are bevelled or pointed as at36.

In the form of engine shown in Figure 2 the. shaft 19 is secured againstlongitudinal move-A ment and the wobble plates are arranged to rotatethe shaft but they slide on it and the feather 37 slides in the key-way38 in 'the shaft. In this construction the two cylinders vare arrangedwith the narrow part of one adjacent the wide part of the other to makea more compact structure.

In' Figure 3, I show four units and each one acts to co-operate with theothers to form a four-cycle engine. Each one rotates effectively as adriving unit for 120 degrees of rotation so thatl they overlap inpropulsion, thus making a smooth running mechanism. In this figure theleft-hand unit i's in the position just prior to explosion and thus atthe beginning of its power stroke. The second cylinder has. just:finished its power stroke and fened the exhaust port 39. Thethird cyliner is in its compression stroke and the fourth cylinder is in itssuction or intake position.

The shafts 40 and 41 are each slidable in the sleeve 42 which is heldagainst any movement longitudinally by the flange 43 and the nuts 44 butrotates in the'bearing 45.

An engine provided with a wobble-plate rotating and also sliding in acylinder eliminates uneven forces or side mot-ions and therefore excesswear on the shaft and the cylinder walls. The absence of valves andpushrods, cam-shafts and other extra parts eliminates the chances ofthese parts becoming disarranged or ineffective and in this respect thisengine is particularly adapted for air-craft purposes.
